Description
The eSync ESP32-C3 Smart Switch Dev Board is engineered for direct integration into AC mains-powered smart home and industrial automation systems. Its core is the ESP32-C3-WROOM-02 module, which combines a 160 MHz RISC-V processor with 2.4GHz 802.11 b/g/n Wi-Fi and Bluetooth Low Energy 5.0, providing a robust wireless foundation for IoT applications. The board’s integrated Hi-Link AC-DC converter simplifies installation by accepting a wide 110-240V AC input range, delivering stable 5V and 3.3V rails to power the logic and relays.
Designed for reliability, the board features two electromechanical relays capable of switching up to 7A loads at 220V AC, suitable for controlling a wide range of household and light industrial equipment. A USB Type-C port provides direct access to the UART for programming and debugging, while GPIO20 and GPIO21 serve as serial pins. The compact form factor and pre-soldered components make it a ready-to-deploy solution for developers building scalable, remotely managed automation nodes with OTA update capability.
